While I haven't tried with static libraries, I think that ``virtualenv`` [1]_ may be very useful for you. With it you can keep a set of packages under your control and still use those installed system-wide. You just run a copy of the Python interpreter also under your control, without having to resort to altering PYTHONPATH or mangling source code before installation. For dynamic libraries, I'd suggest that you installed them under your local directory and compiled local packages against them. If the copy running under your grid nodes happens to be in the same path, you don't even need to set LD_RUN_PATH. I've been using a setup like that for some time and I'm far happier with it than with previous hacks with PYTHONPATH. Just my two cents. ..
